Chemical Structure
Description
CATO supplies 3-((Pyridin-3-ylmethyl)sulfonyl)propanoic acid hydrochloride (CAS 1171755-83-1), a certified reference material (molecular formula C9H11NO4SHCl, MW 265.71 g/mol) for analytical method development and quality control.
Based on its molecular formula C9H11NO4SHCl, 3-((Pyridin-3-ylmethyl)sulfonyl)propanoic acid hydrochloride contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 265.71 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
